Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
